Dive in, in the Under the Sea Happy Nappy Duo™. Featuring playful sea friends including turtles, rays and our shy octopus, this is a perfect design for little explorers.

The Happy Nappy DUO is the most advanced reusable swim diaper in the world, and the only nappy system you will ever need for your Water Babies swim class, as it's a double nappy in one!

The classically form fitting and leak proof outer layer is still the Happy Nappy you know and love, effectively preventing solid leaks into the pool, but inside there is a highly technical active silver inner layer, which is scientifically proven to kill pathogens that cause tummy bugs and sickness - like Cryptosporidium, E.coli and other viruses including COVID 19 - killing these bugs inside the nappy, before they can enter the water. Making the pool safer for your baby and for other swimmers too.

Working with one of the world’s leading virologists and 4 years in development, the silver lining inner layer is extremely gentle on babies skin, but highly effective in destroying pathogens that can be found in faecal matter.

But that’s not all. Because the Happy Nappy DUO has been approved as a Double Nappy System, which means you no longer need to buy disposable swim nappies to wear under the Happy Nappy, saving money and saving the planet by not contributing to millions of tons of disposable nappy waste per year, which can take up to 500 years to break down in landfill!

How it works

The outer part of the Happy Nappy remains the same, waterproof with snug fitting leg and waist bands. These are constructed from specialist grade Lycra that won't lose its elasticity. To fit comfortably there shouldn't be any gaping. The body of the Happy Nappy is made from 1mm thick neoprene and recycled polyester.

Solid matter is kept contained using the waist and thigh ribs of the Happy Nappy while the silver in the under nappy helps to kill any harmful bacteria, viruses and pathogens. The inner nappy is constructed to also be waterproof, with specialist patented silver materials embedded.

This ensures that any liquids leaving the nappy must pass through the silver material, allowing it to kill any pathogens as it does so. Tip any solids down the toilet and wash the nappy in your washing machine. Compostable and/or biodegradable liners can be used in conjunction with the Happy Nappy DUO to make the removal of solids even easier.
